States Chess Cup: Playoffs

States Cup Bracket

 

Wild Card Matches   

With brackets set from the regular season, playoffs began with the first round featuring two wildcard matches: Virginia vs. Minnesota, and Georgia vs. California-South.   

Virginia and Minnesota both brought very similar rosters, with each state having three strong masters and a very underrated fourth board. Virginia, however, won the match convincingly by a score of 11-5, as all four players put in a great day, each scoring above 50% against a Minnesota roster with an average rating of 2195. Virginia NMs Nemanja Milanovic and Isaac Spense, as well as FM Jason Morefield all scored 3/4.      

California-South turned in its own decisive victory over Georgia, with a final score of 11.5-4.5. California-South was led by IM Keaton Kiewra, who went 4-0 as the top board. NM Serkan Salik and the very underrated Hursh Mehta both scored 3/4.    

Divisional Matches  

The second round featured pairings of Michigan vs. New Jersey, Virginia vs. California-South, Iowa vs. Illinois, and California-North vs Washington.    

Michigan built up a healthy lead over New Jersey, heading into the final round with a 7.5-4.5 score. As the higher seed, Michigan held draw odds and only needed a half-point in the fourth round to clinch the match. However, New Jersey proved undeterred by its slim chances, and rallied to win three games of its games. Michigan, however, was saved by this miracle draw from FM Mark Heimann against New Jersey GM Mac Molner.

Our team was up 7.5-4.5 and had draw odds, as the tiebreaks for the division championships were based on the regular season standings (on which we would come out ahead). Thus, to advance in the playoffs, all we had to do in this round was not get swept... } 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 { As a little joke, I faked Mac out a bit with the move order (I played 5...Bb4 when we played in the first round of the States Chess Cup) before transposing into a Scheveningen Sicilian. Lately I've been having some fun playing some "forgotten" Sicilian variations, as at rapid time controls they can lead to enjoyable positions. } 6. g4 { The Keres Attack is the big reason why the Scheveningen is no longer in favor, and players who wish to play similar positions usually angle for them from a Najdorf move order. However, that doesn't mean that White is automatically winning, or that the resulting positions can't be interesting for both sides to play (particularly at fast time controls when there isn't time to work through all the details). } 6... h6 7. h4 Nc6 8. Rg1 h5 9. gxh5 Nxh5 { According to the last time I checked the theory (more years ago than I care to admit, but I imagine it was the same for Mac since like I said, this is not considered to be a critical Sicilian line these days), this is main line. } 10. Bg5 Qb6 11. Ndb5 a6 12. Nxd6+? { Knowing that inviting the Keres is a very provocative way to play, Mac chooses an aggressive sacrificial continuation. There are certainly ways for Black to get checkmated quickly, but with best play I believe he can take the material and hunker down successfully. (Note that the operative word is "best play" ) } 12... Bxd6 13. Qxd6 Qxb2 14. Kd2 Qxa1 15. Bb5 { (15. Nb5 looks dangerous, with the idea that 15...axb5 16. Bxb5 discovers an attack on the queen and, by pinning the knight on c6, threatens mate on e7/d8 while also stopping the Black queen from coming back to defend with 16...Qd4+. However, 15...f6 and the Black king will hide safely on f7 and leave White with too little to show for the heavy sacrifices he has made.) } 15... Qxc3+ 16. Kxc3 axb5 { Black has a rook and two pieces for the queen (plus a pawn and some damage done to White's pawn structure). It is worth noting that White has good control of the dark squares, and it is hard to break White's grip securely: ...f6 is possible, but then the knight on h5 is precarious and the g-pawn becomes weak. So while Black should be much better, it is worth noting that he has nontrivial problems to solve. In a rapid game, this opens up significant practical possibilities for White and pitfalls for Black (as we shall see... ) } 17. Kb2 f6 18. Be3 Ne5 19. Kb1 Nc4 20. Qc7 Nxe3 21. fxe3 { Black has further damaged White's pawn structure and left him with only two pieces left to attack...unfortunately, those two pieces can still do some serious damage if Black isn't careful... } 21... O-O? { I should have played something like 21...e5 to stop White's own advance first. I thought my pieces could patch up my kingside, but a few moves later would show what I missed. } 22. e5 fxe5 23. Qxe5 Rf5 24. Qc7 e5?? { Now the looseness of my knight and fragility of my little remaining king cover prove decisive. } 25. e4 { 25. Qe7, threatening Qe8+ and winning the knight after the rook is forced away by a subsequent e4, is actually decisive. Technically, I can save myself by retreating to f8. But the above line showed what I was missing the whole time... } 25... Rf7 26. Qd8+ Kh7 27. Qe8 { ...the play on the e8 square. Oof. White now wins material and Black's king remains hopelessly exposed, giving White what should be a decisive advantage. When Mac and I played at the beginning of the season, our game had a similar finish: I had an objectively great opening from another obscure Sicilian variation, but some lingering coordination problems of mine and resourceful attacking possibilities conjured up by Mac eventually provoked a decisive blunder from me. I thought this was going to be a repeat of that game, and at the worst possible of times. I was laughing darkly inside. } 27... Be6 { At this point, White can just take my rook on a8 which is likely objectively best, but I assumed that White would a) know that he should be winning whichever free material he takes, and b) not want to worry about various fortress-y constructions with a bishop on c4, knight on f4, etc. So I figured he'd take on e6, and I'd rather give up the bishop than the knight that helps hold my kingside together. } 28. Qxe6 Rf6 29. Qxe5 { Engine says >+7 to White here. But we know that funny things can happen in rapid games, and from here on sheer will to not lose kept me hanging on long enough for funny things to start happening. } 29... Nf4 30. h5 Raf8 31. Qxb5 b6 32. Qg5 Ne6 33. Qg4 Rh6 34. e5 Rf4 { At this point, Mac has won seemingly a million extra pawns to go with his queen vs rook and knight, and of course my king remains exposed. However, White doesn't have a clear breakthrough (it's hard to create a passed pawn on the queenside, the e-pawn is blockaded, and my janky third-rank rook and knight barrier actually keep the checkmates at bay well enough). While the engine still proclaims a huge advantage to White, it can be a bit frustrating to play. And Mac was getting low on time... } 35. Qe2 Rh4 36. Rg6 Rxg6 { 36...Rhxh5?? 37. Rxe6! Rh1+ 38. Kb2 Rxe6 39. Qe4+ would have been a nifty way for White to finally put me out of my misery. I have no doubt this was Mac's plan, so I'm glad I saw this and picked a non-blundery way to recoup one of the many pawns I was down. } 37. hxg6+ Kxg6 38. Qb5 Kf5 39. Qxb6 g5 { So now White has his goal--two queenside passed pawns--but Black has a dangerous passed pawn of his own. I was starting to feel like I'd actually have a chance, particularly in light of the upcoming time scramble. } 40. a4 { A gift. Time trouble hits right away. } 40... Rxa4 { Now the engine doesn't even say White is appreciably better. (Of course there's still time for me to conveniently fork away my rook) } 41. Qf2+ Rf4 42. Qg2 Kxe5 { Got 'em all back! } 43. Kc1 g4 44. Kd2 Nc5 45. Ke3 Rf3+ 46. Ke2 Rf4 47. Qh2 { Given the match situation, where every NJ player needed to win for their team to advance, of course Mac can't take a repetition. With just four seconds left on his clock (I had 21) he needs to find a way to play for a win... } 47... Ne4?? { ...and I give it to him! } 48. Qh5+ { 48. Ke3! g3 (of course my intention behind 47...Ne4), but now White has 49. Qh5+ Rf5 50. Qe8+, winning the knight by skewer. Of course, to be fair to Mac (and myself), this is some fancy queen footwork to see in split seconds. } 48... Rf5 49. Qh8+ { Should have just taken the g4 pawn, but I'm sure we both had the lingering feeling that White should have had been able to force something crazy with some crazy queen footwork, and Mac's intuition was probably leading him to try to find it. } 49... Kf4 50. Qb8+ Kg5 51. Qg8+ Kf4 52. Qb8+ Kg5 53. Ke3 { Again, I was fine with a repetition but under the circumstances it was unacceptable for Mac. } 53... Nf6 54. Qd8 g3 55. Qd6 Kg4 { But now if either side is making progress it is Black. } 56. Qd4+ Kh3 57. Qd1 g2 { Black's pieces ended up being chased into position to support the g-pawn and somehow, Black should be winning. } 58. Ke2 Re5+ { If I really just wanted the draw, 58...Rf1 nets it immediately (via the immediate 59. Qxf1 or 59. Qd3+ Kh2 60. Qd6+ Kh1 61. Qc6 Kh2). } 59. Kf2 Ng4+ 60. Kf3 Re3+ 61. Kf4 Rg3 62. Qg1 Nh2 63. c4 Rf3+ 64. Ke4 Rf1 65. Qe3+ Nf3 66. Qh6+ Kg3? { 66...Nh4 and the checks will soon run out, whereupon Black will promote and win. But I too was practically out of time, and I knew that all we needed was a draw. So under the circumstances, while I wish I were a stronger chess player capable of quickly seeing the right moves, I'm glad I went for the practical decision and didn't somehow find a weird way to checkmate myself or something while trying to play for a needless win. } 67. Qf4+ Kh3 68. Qh6+ Kg3 69. Qf4+ Kh3 70. Qh6+ { Draw by repetition. } 1/2-1/2 [/pgn]
 

Virginia and California-South entered with some heavy firepower on the top boards: Virginia had two FMs and a NM, while California-South had IMs on boards 1 and 2. The match was tight after two rounds, but Virginia produced a great third round and scored 3.5 points from those four games, including wins against both IMs. Virginia went on to hold this lead, winning by a final score of 9.5-6.5.

1. d4 {My opponent was Board 1 for his team and had been playing consistently
well throughout the States Chess Cup, so I determined going into this game
that I would be happy with any result that wasn't a loss. However, this didn't
mean I would play for a draw, far from it...} d5 2. c4 e6 3. Nc3 Nf6 4. cxd5
Nxd5 5. e4 Nxc3 6. bxc3 c5 7. a3 g6 $5 {I had only discovered the existence of
this move about half an hour before the match began, so needless to say I was
grateful for the time I spent preparing that day! I went with what I had
determined was the most principled response.} 8. Nf3 Bg7 9. h4 Nc6 10. e5 h6
11. Bd3 b6 12. Be3 Bb7 {Here the position can be said to be roughly balanced,
although White has a bit of an edge. However, my next move was a mistake that
showed how unfamiliar I was with this structure.} 13. h5 $6 g5 {The reason
this move is a mistake is twofold. Firstly, Black has the additional
possibility of ...g4, undermining my center. Secondly, I no longer have the
ability to pressure the pawn on h6, and it's entirely possible that my pawn on
h5 simply becomes weak. My control over the b1-h7 diagonal isn't as important
as I initially thought it was.} 14. Qe2 cxd4 15. cxd4 g4 $2 {The computer
marks this pawn grab as a mistake.} 16. Nd2 $2 {And this as well!} (16. Nh4 $1
{The computer strongly prefers this move, but the reason why is not at all
clear until it is examined more thoroughly.} Nxd4 17. Qxg4 Bxe5 {So what
happens if Black plays like he did in the game!} 18. Rd1 $1 {For one thing,
Rd1 comes with a threat that is not easily defended against.} Nc6 19. O-O Qe7
20. Be4 Bf6 21. Ng6 $3 {Another reason is that Ng6 is a possibility now! So
the reason the computer prefers Nh4 becomes clear: the pawn grab Black did in
the game is too risky when White can sacrifice a knight to g6, so he has to
leave his pawn on g4 vulnerable, giving White an edge. Although there are more
variations, I will not go too in-depth here as it was just a rapid game.})
16... Nxd4 17. Qxg4 Bxe5 18. Rd1 {I played this move because I was concerned
about Nf3+ ideas and I wanted to pressure the center. Black has only one move
after this which retains his advantage, which neither I nor my opponent was
able to find in the game.} Nc6 $6 {Retreating gives White a chance to activate
his pieces and obtain actual compensation for the missing pawn.} (18... Ke7 $1
{This would have been best, stopping any Bb5+ ideas forever and threatening
Rg8. However, such a move is difficult to see when you are still considering
castling queenside as a viable option. Black would have a small advantage here,
although White would have good practical chances.}) 19. Nc4 Bc3+ 20. Kf1 Qe7
21. Be4 Ne5 $6 {This move is dubious because of what was played in the game.
However, exchanging pieces when under attack is a very natural thing to try,
especially when it comes with an attack on the queen.} 22. Nxe5 Bxe5 23. Bxb7
Qxb7 24. Bxh6 $1 {This is most likely what my opponent missed.} Rd8 $4 {
This should have lost on the spot, but with the game approaching time-trouble 
(which in a rapid game means only a few minutes are left for the entire rest
of the game) I was unable to find the precise refutation.} (24... Rxh6 25. Qg8+

White is better thanks to his passed h-pawn, but Black is fighting.}) 25. Rxd8+
Kxd8 26. Bg7 Bxg7 27. Qxg7 Re8 28. h6 $2 (28. Rh4 $1 {This last precise move
stops Qd5 and guarantees two things: that White has a few more moves before
Black generates real counterplay, and that Kg1-h2 is now a viable option. This
is all he needs to convert the win.}) 28... Qd5 $1 {Now Black obtains actual
counterplay and White's win becomes very complicated.} 29. Qg4 Qe5 30. g3 Ke7

Iowa and Illinois both featured balanced lineups, with the difference between Iowa’s boards 1 and 4 only 123 points. Illinois had lost to Iowa in the regular season but was determined to flip the script in playoffs, and entered the fourth and final round with a 6.5-5.5 advantage. The States Cup saw another come-from-behind finish, however, with Iowa winning 3.5/4 games in the last round to advance. Iowa was led by a 4-0 performance by NM Joseph Wan on the top board, and NMs Tim McEntee and Kushan Tyagi also produced critical victories, scoring 2.5/4 and 2/4 respectively.

I once again took first board against Illinois, as NM Arshaq Saleem (2276) was unavailable for the match.

Last time they had come with a roster of 2400, 2350, 1900, 1900. Now we were in the first round of the playoffs, with the loser going home. Illinois fielded a more balanced lineup.

On the surface it just loses a pawn, but Black's pressure on "d4" is good to win back the pawn should White take with the knight. If White takes with the pawn, then the doubled pawns are weak and Black will get rapid development and eventually win back the pawn starting with 5... Nf6.} 5. e5 $5 (5.

Both California-North and Washington featured strong top boards. With two 2400-strength players, California-North jumped to a quick 3-1 score after the first round and maintained that lead through round two. Washington however, featuring three National Masters, turned the match around by scoring 6.5/8 over the last two rounds, advancing from the quarterfinals as the only upset win.     

Semifinals   

Down to four teams, Michigan took an early 3-1 lead in the first round of its match with Virginia, including a big upset win by 1841-rated Ryan Wang against FM Jason Morefield in mutual time trouble. Virginia fans hoping for another comeback were left disappointed, however, as Michigan held that lead through the last three rounds to win the match 9.5-6.5 and secure its spot in the finals.

Washington and Iowa had a combined six National Masters and one International Master, virtually guaranteeing some high-quality games. The match was back and forth with each round, with Iowa scoring 2.5/4 in the first round, Washington scoring 3/4 in the second round, and Iowa repeating 2.5/4 in the third. However, Washington took the match after scoring 2.5/4 in the final round, advancing to the finals.

Washington vs. Michigan in the States Cup Championship
Image Caption
After 10 weeks of play by nearly 30 state teams, Washington and Michigan met in the 2020 States Cup Championship.

After 10 weeks of hard-fought chess through a regular season and playoff bracket, the States Cup was at last down to two final teams: Washington and Michigan. Both teams submitted top-heavy lineups, with Washington sending three NMs and an Expert; and Michigan with an FM, two NMs, and a Class-A player.  

After splitting the first round, both Washington NMs Derek Zhang and NM Rushaan Mahajan scored wins in the second round, though Michigan held winning positions on the other two boards and appeared to be heading toward round equalization. But Washington top board NM Kyle Haining pulled out a draw in a wild time scramble with Michigan NM Tony Nichols, and Advaith Vijayakumar did one better – first turning a losing position into a drawn endgame, then walking away with the full point after a mouse slip by his opponent NM James Canty.

Brings back memories of my good old days--or as they say, what comes around goes around!} 1. d4 Nf6 2. Nc3 { I played a really fun Veresov last week in the semifinals, so I figured why not have another go.} d5 3. Bg5 c6 {Nothing wrong with playing solidly like this, but White can double Black's pawns at any point, and my personal preference is to not give Veresov players what they probably want so easily (3. ..Nbd7).} 4. Qd2 Bf5 5. f3 h6 6. Bxf6 exf6 7. e4 dxe4 8. fxe4 Be6 {I get that Black has free development and the bishop papir, and can play for pawn breaks or piece pressure against my center. Still, letting me get in e4 and have the center like this probably really is giving me what I want though, with less fuss than Black could have mounted.} 9. Nf3 Be7 10. Bd3 Bg4 11. Ne2 O-O 12. O-O {Probably should have castled queenside. I didn't want to take many risks, because I could feel that for whatever reason(s), my focus seemed to be poorer than I'd like and my decision making seemed a bit sluggish. (For example, I was already starting to fall somewhat behind on the clock, without a particularly good explanation for doing so.)} Nd7 {Again, I think Black could play more energetically with 12...c5, and all of a sudden my center does seem a bit rickety.} 13. c3 Qc7 14. Qf4 {Again, I wanted to slow down the pace of the game to match my own psychological pace at the time, but this was probably not the most testing way to play on my part. I'm more likely to be able to play aggressively, so might as well keep the queens on.} Qxf4 15. Nxf4 Bd6 16. Nd2 g5 $6 {The f-pawns may not be the end of the world, but I'd be very reluctant to saddle myself with such long-term weaknesses without a very good reason in mind, which I don't see for Black (and were not revealed by the next several moves).} 17. Ne2 Rfe8 18. Rae1 Rad8 19. Nc4 Bc7 20. Ne3 Be6 21. Nc1 $6 {Kind of passive and takes its eye off the f4 square. I didn't think this would be a problem and thought it would be just fine if Black wanted to trade off his bishop pair, but I didn't foresee everything that could happen on the e-file. Something like 21. Bc2 would have been better (21...Bxa2 22. b3)} Bf4 22. g3 Bxe3+ 23. Rxe3 Kg7 {23...c5! and now the pin on the e-file stops me from going d5, so once Black exchanges on d4 then both rooks will be well-placed to put pressure on my center.} 24. Nb3 Re7 25. Kg2 Rde8 26. Ref3 { I thought I was out of the woods regarding pins, because all my rooks were off the e-file. Right?} f5 {Wrong. There are also diagonals to pin me on (27. exf5 Bd5) A nice opportunity spotted by Rushaan to off-load the "long-term" weakness I mentioned earlier.} 27. Nd2 {With the idea 27...fxe4 28. Nxe4 Bd5 29. Nd6, and although I give up an exchange on f3, I win it back with the fork of the rook on e8 and the threat to fork again on f5.} f6 {Humorous. It's still tough for me to relieve the tension, because I can't take on f5 yet (unless I want to sacrifice an exchange).} 28. Kg1 {OK, finally I'm threatening exf5 without giving up an exchange, so the tension has to be relieved now.} fxe4 29. Nxe4 Bh3 {Uncovering an attack on e4, and of course I wouldn't want to walk into a pin on the e-file to defend the knight with 30. Re1. But we both doubtless anticipated the same Nd6 motif mentioned earlier, which just results in some even material exchanges.} 30. Nd6 Bxf1 31. Nxe8+ Rxe8 32. Kxf1 Nb6 {I was hoping to nurse something out of a bishop versus knight and black's backward f-pawn, but Rushaan played more energetically than I and never let those possible advantages meaningfully materialize.} 33. Rf2 Nd5 34. Re2 Ne3+ {It takes some nerves to self-pin your own knight, but Rushaan correctly saw his night had enough checks to give my king if I tried to exploit it (many that are also pawn-winning forks). I started realizing I was not going to be better.} 35. Ke1 Kf8 36. h3 {Consistent with my earlier intuition, I wanted to lock down Black's kingside, but again, Rushaan wouldn't give me the time to make that happen.} Kf7 37. g4 Ng2+ 38. Kf2 Rxe2+ 39. Bxe2 Nf4 {And now White doesn't have time to defend the h-pawn and maneuver a bishop or king to further control f5. Black will trade off his backward f-pawn and likely get an outside passed pawn on the kingside. White is not winning this endgame.} 40. Bc4+ Kg6 41. Kg3 f5 42. Bb3 Kf6 43. Bc2 fxg4 44. hxg4 h5 { There it goes. White's last kingside pawn disappears, and even if Black were to lose the g-pawn it probably wouldn't be enough for white to win on the queenside alone. Granted, White should probably be able to stop the g-pawn and the game should be a draw, but ya know, with my decision making being what it was, we can't necessarily count on even that.} 45. gxh5 Nxh5+ 46. Kg4 Nf4 47. Be4 Ne6 48. d5 cxd5 49. Bxd5 Nd8 {I hoped I could make something of the corralled knight, but of course not. I don't have enough other pieces or time to take any advantage of it.} 50. c4 b6 51. b4 Ne6 {At this point I saw that 52. Bxe6 Kxe6 53. Kxg5 should be a draw. 53...Kxe5 54. c5, and I force the trade of all but Black's rook pawns. Black will win all my queenside pawns but my king will come easily to trap the king on the side of the board. This is where I blame my poor decision making--I still hoped that somehow my Rushaan would blunder and I'd win, although there really aren't many other ways for him to go catastrophically wrong and there are ways for me to mess up with the outside passed pawn and his king having direct access to the queenside. I should have just accepted my fate instead of leaving open the theoretical possibility of a win that would never happen, at the objectively greater risk of an L that I could immediately avoid.} 52. a3 $2 {Because there was no point in not taking on e6 and immediately sealing the (fair) final result. Obviously, an ironic move to tacitly "play for a win" with.} Nf4 53. Bf3 Nd3 54. Be2 Ne5+ 55. Kg3 Kf5 {And just a few moves later I had to admit that it was time to try to bail out.} 56. c5 bxc5 57. bxc5 Ke6 58. c6 Nxc6 59. Kg4 Kf6 60. Bb5 Ne5+ 61. Kg3 Ng6 62. Ba6 Ne5 {At this point, I should try to rush my a-pawn as far up the board as possible (without losing it) so that Black's a-pawn will be able to advance as little as possible. This would help me in the likely event that Black jettisons his g-pawn and rushes over to win my a-pawn. 63. a4 makes sense (though I should be careful about advancing it to a5 while my bishop is on a6, less Black traps it on a5 and wins it for free with the knight).} 63. Bb5 Ke7 64. Kf2 Kd6 65. Ke3 Kc5 66. a4 Nc4+ 67. Kf3 Nd6 68. Bd7 Kb4 {And now we pretty much have it as discussed: Black will try to win my a-pawn and advance his own while shouldering off my bishop with his knight. My king will be on the other side of the board and it will be a long route back. However, if I am careful, I should be able to buy my king time, as Black's a-pawn has a long way to advance and multiple light squares where it will need to get past my bishop.} 69. Kg4 Nc4 70. Kxg5 Nb6 71. Be6 $2 {For some reason, I thought that a2 was the only square where I could mount a defense, but obviously by guarding a4, I could make Black have to take a few extra moves to maneuver his knight to b5 before advancing his pawn past a4. This move isn't a blunder, but it shows again that my analysis and decision making was clearly not up to snuff tonight.} Nxa4 72. Kf4 Nc5 73. Bf7 a5 74. Ke3 {Threatening to bring my king to the corner via d2, so Black has to shoulder it off.} Kc3 75. Ke2 $4 { Like I said, I completely forgot about the possibility of controlling a4, and so I thought I had lost as by this point I saw that black's king would keep mine out. (75. Be8, and as I finally saw right after playing Ke2, and the position is a clear draw. Black's knight will need to block my bishop's access to the a4 square to prevent me from sacrificing it for Black's remaining pawn, but it can't do that without the king coming back to support it and letting my king to the corner where it will easily defend.)} a4 {and now it's over. On b2, the king can keep my king away from the queening square and help the knight shoulder off my bishop.} 76. Kd1 Kb2 77. Kd2 a3 78. Bg8 Nb3+ {White resigned (79. Bxb3 Kxb3 80. Kc1 a2 and the black pawn is just in time to hedge off its own path to coronation). Congratulations to Rushaan, who had a great night beyond this round, and to the Washington team, who routed us 3.5-0.5 in this round and put us in a hole from which we could not recover.} * [/pgn]

Michigan scored 3/4 in the third round to cut into the deficit, but in the fourth Washington held its lead by winning the two boards with a rating advantage, and drawing the two boards with a disadvantage.

Team Washington's Jacob Meyer hoists the new traveling States Chess Cup.

With this 9.5-6.5 win over Michigan, Washington became the first-ever States Chess Cup Champion, getting its name etched on the traveling championship cup. Iowa won third place over Virginia. Medals will also be sent to players from each of those final four teams as a reward for their hard-fought seasons.  

Thanks to an incredible initial response to the first States Chess Cup, a second season of the league has been announced. The league is now collecting feedback, so that it may work even better next year.
